A Klingon battlecruiser is destroyed by the USS Constitution inside the Sol system in 2245.

Despite remaining on shakedown-status, the Constitution prototype was instrumental in stopping the attempted theft of the NX-0002 vessel when Klingon agents boarded the unnamed construction project during a cadet cruise. (TOS - Crewcomic: "Shakedown")

While the ship was recorded as lost, both The Wounded Sky and the Starfleet Command games list this ship as active in the two decades following. It is possible the vessel was recovered, although no such explanation exists in currently-published sources.
